To facilitate the evacuation, a one-off assisted departure was being arranged by the embassy to transport Australians to Amman, Jordan, the statement said.

Once in Amman, Australians would be responsible for their own costs and arrangements, including for onward travel.

No plans are in place for further assisted departures.

The government also updated its travel advice for Israel and the Palestinian Territories, warning Australians against travelling to the Gaza Strip due to the high threat of mortar and rocket fire.

"We strongly advise you not to travel to the Gaza Strip because of the extremely dangerous and unpredictable security situation and the possibility of further Israeli military operations. Australians in the Gaza Strip should depart immediately," the advice on the Smart Traveller website said.
